Background technology
This equipment for example is to be used for the so-called aerial head that " light radio " used, and it also will describe in detail below.
Light/electric converting unit is converted to the signal of telecommunication to light signal.The frequency of light carrier ray for example at 187,000,000,000,000 hertz (Terahertz) in the frequency range of 1,000 ten thousand hundred million hertz (Petahertz) or have wavelength from 1.6 microns to 300 nanometers, that is to say, also comprise visible light.Radio signal for example is modulated on the light ray.This radio signal for example has from 3 megahertzes (Megahertz) to 100 Gigahertzs (Gigahertz) or one or more higher carrier frequency, particularly one or more carrier frequency in from 1 Gigahertz to 60 gigahertz range.For example this radio signal is mobile radio signal or WLAN signal (Wireless Local Area Network (WLAN (wireless local area network))).
On the contrary, electricity/optical conversion element is the electrical signal conversion in the described frequency range light signal of described light frequency scope.Antenna element is harmonious with the carrier frequency of this radio frequency aspect its structural type.
Especially when for example be implemented in two converting units in the unique element, particularly in the semiconductor element that forms with the monocrystalline inorganic material time, the expense of this device fabrication is very high.
Summary of the invention
Task of the present invention provides a kind of equipment and a kind of simple method that is used to move this equipment of simple structure.Particularly this equipment should not rely on supply power voltage or with little supply power voltage work, particularly less than 5 volts or less than 1 volt.
The task of relating to described equipment solves by the equipment with the feature that provides in claim 1.Expansion provides in the dependent claims.
The present invention is from such consideration, promptly when two converting units spatially with function on when being separated from each other, this equipment can be made simply.Particularly concerning each converting unit, allow not rely on another converting unit use thus and on corresponding conversion direction, have high efficiency converting unit.In addition, the present invention is from such consideration, promptly particularly passive operation or allow to use the simple equipment made from the operation of little supply power voltage because need not provide other voltage source, that is particularly do not need the electrical network parts, battery or storage battery or similar voltage source.
In an expansion of the present invention, described equipment does not comprise externally fed voltage.Therefore the energy of operation only obtains from the light of arrival or from the electromagnetic radiation that arrives.Therefore do not need to be used to produce the circuit engineering expense of supply power voltage.Also save the maintenance costs of safeguarding voltage source.
Therefore use polymer modulator in an expansion of the equipment that is used for the electric to optic converter unit.Polymer modulator only allows the conversion of the signal of telecommunication to light signal.Polymer is that molal weight is for example greater than 10 4Gmol -1Big molecule.Particularly use organic polymer or other polymer.For example use a kind of polymer modulator, it comprises the polymer electric field orientation or so-called polarization.This means a kind of like this material of use, a kind of material with strong nonlinearity electro optic effect is coupled to or is diffused in a kind of polymer with less dielectric constant in it.Make the material that is produced stand a kind of electric field directional process, make to produce a kind of material with big dielectric constant or electro-optic constant.Yet the polymer modulator that also has other operation principles, for example intrinsic polarization from form the color development superstructure (intrinsically polar Self-Assembled chromophoricSuperlattices, SAS).
Thereby polymer modulator is compared with the single crystal semiconductor element and can be made with more simple mode and expense preferablyly.Polymer modulator allows passive operation in addition.Therefore produce a kind of aerial head that is used to transmit and receive data or equipment, it can be simply and the manufacturing that suits of expense.Can instead realize new application economically thus, for example construct a large amount of so-called junior units (Pikozelle), that is have less than 35 meters the reception or the radio unit of transmission diameter.
In an expansion of this equipment, electricity/optical conversion element is to use the modulator of interference work, particularly Mach-money Dare (Mach-Zehender) modulator.Interfere by producing two interior differences running time of optical transmission distance.Laser especially is fit to produce the obviously interference of (ausgepraegt).
In next one expansion, and electricity/optical conversion element (14,14a) be electroabsorption modulator.Electroabsorption modulator is based on Fu Langzi-Kai and this (Franz-Keldysh) effect of enlightening or its adverse effect.Yet except electricity/photoelectric absorption modulator, diode also provides the possibility of structure passive antenna head as light/electric converting unit, and it has dramatic benefit, for example about the efficient of light/electricity conversion or about avoiding influencing each other of two kinds of translation types.
Electricity/optical conversion element may also comprise other element, for example filter.Light/electric converting unit also may also comprise other unit, for example filter.
In another expansion of equipment of the present invention, light/electric converting unit is an optical diode, particularly photodiode.Particularly suitable being to use has between conduction band and valence band the directly semi-conductive semiconductor diode of band transition, that is silicon diode for example.Both used diode also to use and had the diode that PIN ties (p mixes, intrinsic is mixed, n mixes) with p/n knot.Therefore need not use based on connecting semiconductor or have semi-conductive your assembly of the non-direct transformation of interband (promptly having knot) herein, the energy change in electronics or so-called " hole " not only in knot, and also its pulse also changes.
In another expansion of equipment of the present invention, antenna is connected on circulator unit or the optical coupling unit.By using circulator unit or optical coupling unit that a unique antenna can be used, make it possible to depend on employed antenna and cost saving on each equipment.Avoid undesirable feedback by using circulator unit or optical coupling unit in simple mode.
The also passive work in circulator unit or directional couple unit in an expansion, that is it does not have outside supply power voltage splicing ear.Entire equipment also keeps passive states thus.
In the expansion of another replacement, use two antennas in contrast, so that do not need circulator unit or directional couple unit.This variant especially uses when the price of antenna is lower than circulator unit or directional couple unit.
Comprise connection device at equipment described in the next one expansion, it is suitable for connecting optical fiber, by this fiber data on both direction, be transmitted in both directions.Optionally scheme is that described equipment comprises two connection devices in addition, is used to connect two optical fiber.This connection device is the part of threaded connector in next one expansion, that is it has internal thread or external screw thread.Therefore optical fiber can be connected with this equipment with the better way methods.
The present invention relates to a kind of method that is used to move equipment of the present invention in addition.In this operation method, according to multichannel multiplexing method the terminal equipment transmission data of the network that differs from one another of heterogeneous networks standard by this equipment.Suitable multichannel multiplexing method is the method for time division multiplexing, frequency division multiplex, code division multiplex particularly.
Be the terminal equipment transmission data of at least two kinds, at least three kinds or the network standard below all in an expansion:
-DECT (Digital Enhanced Cordless Telecommunication (numeral strengthens wireless telecommunication)),
-GSM (Global System for Mobile Communication (global system for mobile communications)),
-UMTS (Universal Mobile Telecommunication System (Universal Mobile Telecommunications System)),
-WLAN (Wireless Local Area Network (WLAN (wireless local area network))) and
-WiFi。
But with the present invention or the related information transferring method that also uses other of its expansion.
In order separately to be used for the signal of heterogeneous networks, in described equipment, for example use passive filter.The antenna that is fit to various criterion also in parallel.
Summarize and say, for example provide a kind of aerial head that passive " light radio " used that is used for.A kind of like this technology of notion " light radio " expression, use this technology part or all of the signal that will transmit in base band or in radio bands by optical fiber such as glass fibre or polymer fiber transmission.For example Xia Mian situation is feasible, promptly is modulated to signal on the light in the glass fibre and has been loaded with whole radio-frequency informations and directly outputs on the antenna after light-electricity is changed.At this moment, the RF energy of being launched (RadioFrequency (radio frequency)) can directly produce from this light, and the RF signal that receives can directly be modulated this light again and for example arrive another frequency, makes it possible to achieve the passive antenna head that only connects by glass fibre or plastic optical fibre.A kind of application examples provides signal by the radio junior unit of wireless data transmission network in building in this way.
The problem that is run into when realizing such aerial head relates to technology in the future, so that can not employ hitherto known solution immediately.Described aerial head is integrated on a polymer wafer or the polymer chip.The light of " downstream optical fiber " is divided into two parts by beam splitter; A part is the signal of telecommunication with the photodiode converts that is fixed on the polymer chip, and another part is by polymer modulator, and the latter is by the radio signal power supply that receives, and this radio signal for example sends from mobile device.For example electric circulator separates RF upstream and RF downstream.Therefore can use low-cost polymer assemblies, so that the price of aerial head is eased down to several Euros.
